The goals of the program are to evaluate the effectiveness of agricultural conservation practices, identify underlying processes that affect water quality, and develop technologies to target critical areas of the landscape. Funded projects provide current and accurate scientific data on the environmental impacts of agricultural practices and help to develop or revise agricultural practices that reduce environmental impacts while maintaining farm profitability.
The DNR works with the Minnesota Geological Survey (MGS) to convey valuable geologic and groundwater information and interpretations to government units at all levels, but particularly to local governments, private organizations and citizens.
The Drinking Water Contaminants of Emerging Concern (CEC) program identifies environmental contaminants for which current health-based standards currently do not exist or need to be updated, investigate the potential for human exposure to these chemicals, and develop guidance values for drinking water. Contaminants evaluated by CEC staff include contaminants that have been released or detected in Minnesota waters (surface water and groundwater) or that have the potential to migrate to or be detected in Minnesota waters.
The DNR works with the Minnesota Pollution Control Agency and the Minnesota Department of Health to determine the level of contamination from mercury and other harmful chemicals in fish from Minnesota's lakes and rivers and to track the success of efforts to reduce mercury pollution. Clean Water Legacy funding is being used to significantly increase (more than double) the number of lakes and rivers that are assessed for mercury contamination on an annual basis. Fish are collected during DNR fishery surveys, processed for laboratory testing, and analyzed for contaminants.
The Index of Biological Integrity (IBI) is a tool that can identify water pollution problems based on the type and abundance of selected plants or animals. The Minnesota Pollution Control Agency (MPCA) uses IBIs for fish and macroinvertebrates (stream-dwelling insects and other critters) in streams to help determine whether these waterways are impacted by water pollution. The DNR has developed a similar tool for fish in lakes and is developing a tool for aquatic plants. Both are used to help the MPCA identify lakes that may be impacted by water pollution.
The objective of this project is to build on previous efforts aimed at determining the public health risk due to virus contamination in Minnesota groundwater. The Minnesota Department of Health will examine the occurrence of viruses in non-disinfecting groundwater sources in Minnesota as well as evaluate the association between source water virus occurrence and community acute gastrointestinal illness.
Staffing support to evaluate the performance of existing stormwater infiltration sites, as identified in the Minimal Impact Design Standards (MIDS) project. Monitor the range of existing infiltration devices in Minnesota and compare to design criteria, maintenance records, and quantify year-round infiltration rates. Develop and refine pretreatment options and standards for municipal stormwater treatment.
The goal of this project is to update and revise the Twin Cities Metro Area (TCMA) Chloride Management Plan to a Statewide Chloride Management Plan (CMP). The Statewide CMP will provide stakeholders the information and tools necessary to improve and/or maintain water quality with respect to chloride.
The goal of this project will be to research and develop statewide winter maintenance best management practices (BMPs) for inclusion in the Statewide Chloride Management Plan and Winter Maintenance Assessment tool (WMAt). The WMAt is a necessary technical resource and planning tool for stakeholders and permittees to implement the chloride reduction strategies described in the Statewide Chloride Management Plan.
This project will conduct on-going sampling and lab analysis for suspended sediment concentration at select sites. It will also develop real-time continuous suspended sediment concentration measurements using turbidity and Acoustic Doppler Velocity Meter sensors, data analysis and draft United States Geological Survey (USGS) Scientific Investigations Report, and comparison of sampling and laboratory methods for total suspended solids and suspended sediment concentrations.
The Legislature created the Statewide Survey of Historic & Archaeological Sites to provide opportunities to expand our understanding of historic and archaeological sites statewide.
Projects are defined by an oversight board and are conducted through competitive-bid contracts.
MNHS continues to strive for environmental, economic and social sustainability in its sustainability program. To pinpoint opportunities for ongoing progress, the sustainability program will harmonize a broader range of institutional needs and objectives. The program will establish integrated, continuous, electronic reporting that unites environmental, social and economic risk analysis. This reporting will be used to further reduce our environmental impact and improve the sustainability of our operations as a whole.
This project delineates and maps watersheds (drainage areas) of lakes, rivers, streams, and wetlands for the state of Minnesota and provides watershed maps in digital form for use in geographic information systems. These maps become the basis for clean water planning and implementation efforts.
The DNR's Regional Clean Water Specialists and Area Hydrologists work with other state agencies and local partners to help identify the causes of pollution problems and determine the best strategies for fixing them. A statewide coordinator works with the DNR and external partners to ensure funds are spent in the most effective and efficient manner to meet the State's clean water goals.
The DNR provides technical support regarding the causes of and solutions to drainage impacts, actively engaging with other Minnesota modelers and scientists working on issues related to altered hydrology. We use state-of-the-art models to look at cumulative impacts of drainage and land-use practices and determine the benefits of site-specific best management practices. This involves collaboration with multiple partners and at multiple scales.
The goal of this project is to maintain and make enhancements to the Winter Maintenance Assessment tool (WMAt), which is a necessary technical resource and planning tool for stakeholders and permittees to implement the chloride reduction strategies described in the Chloride Management Plan.
